To all whom t may concern.'

Be it known that I, JOSEPH N me, a citiresiding at Chi- Illinols, have invented certain new and useful Improvements in a Door Holder, of which the following is a specification.

p This invention relates to door holders and has for its object to provide means for use in conjunction with door checks or return members which will permit holdingy the doorl in any desired open, or' partially open position, this being an improvement on the invention disclosed in my Vearlier Patent 1,241,478 patented September 25th, 1917. In the instant application I have disclosed a structure which may be readily applied to existing door checks which may be` manually operated when the door is in the desired position to maintain it in such position and which is so constructed that a further slight opening movement of the door will move the holding device out of operative position and permit automatic closing or further opening of the door.

Another object consists in the provision of means yieldably holding the engaging member in engaging osition, which means is constructed -to yiel ably hold the engaging member out of engaging position., Another object consists in constructing the detent or holding mechanism in such wise that it may be readily reversed to accommodate the attachment of the door check to differently mounted doors, or to doors swinging in either direction.

Still another object consists in the provision of operating means to a door, or the like, to actuate the holder at a point distant from the door check. Y

These and other objectswill be more fully explained and described in the following speciication and shown in the accompanyin drawing in whichigure 1 is a front elevation of a portion of a door showing a door check and mechanism embodying my invention applied F1 2 is a plan view of the same drawn to aarge scale showing the pawl in holding position.

Fi 3 is a similar view showing the awl in re ease position and yieldably hel by the sear member.

tion of the door check arm and ratchet broken away, for illustration.

Fig. 5 is a front elevation showing operating means for operating the door holder at a point distant from the door check.,

10 indicates, generally, a door check of conventional constructionK as applied to a door, it being well known `to those skilled -in the'art that these devices comprise, generally, a shaft l11 whose movement from normal position is restricted -by a spring, fluid, or both, or other means; these means also acting to normally return the shaft to normal, or door closlng position. .An arm 12 is secured tp the shaft to rotate therewith and is pivotally attached at one extremity to a second arm 13 which is attached to the wall, jamb, or the like. It will be understood that these details are not an integral part of my invention and I do not wish to be considered as restricted to any particular form or arrangement of them except as necessary to the proper functioning of thedoor holder mechanism.

I provide a ca or cover plate 14 at the top of thedoor c eck which may be substi-j tuted for that ordinarily provided, or in the attachment of my door checks, may be casin Thls cap 14 is stationary with a projectile mounted u on t e ratchet 16 p 16". A cap vscrew 17 is threaded into the arm 12 and has a. rojectin tip 17 engaging one of the note es 16, t is construction permitting attachment of the arm 12 in any adjusted position to and with respect to the cap 14. Coactable with ratchet 16 is the pawl 18 having the opposed engaging lugs 18 provided with the an lary dis osed stem 18 extending throng the paw into the projecting portion 14* of cap 14. At the lower extremity of the stem 18 is the arm invention to existing secured to the cover or and provided portion 14. Rotatably cap 14, yis a toothed aving the serrations or notches 19 by means of which the pawl 18 may be 3, a corner 18c thereof will ride'into the notch 2Oa and be yieldably maintained in such position by the sear 20. A spring 25 is attached to the projecting end of the sear 20 at one end and at the other to a screw 26 projecting outwardly from the cap 111 or other suitable location. The free end of Sear 20 is preferably downwardly bent as indicated at 20c in Fig. 4, for example. 'llhe spring 25 maintains the sear in position pressing against thepawl 18 as will be obvious and thus insures retention ot the pawl in release position by the notch 20a, as shown in Fig. 3. l1`he provision of a pair of notches 20a and a pair of apertures 20b permits reversal of the sear to accommodate reverse mounting of the'door check. 'llhe pawl is likewise constructed for reversal, it being merely necessary to move plate 14 180 and rearrange the pawl and sear 20 for such reversal.

ln the use of my device when the door has been swung to position in which it is desired to be maintained, the arm 19 may be moved inwardly to engage pawl 18 with ratchet 16, after which, upon release of the door, the return mechanism will force the ratchet against the pawl in engagement.

ln order to actuate the holding mechanism when it is used with high doors, or where the door swings against a wall or the like, l may find it desirable to apply operating mechanism and l have illustrated such mechanism in Fig. 5. An arm 30 is provided pivoted at one extremity at 30a to a projecting bracket 31 secured to and projecting rom the cap 14. At its other'extremity the arm 30 is apertured to permit the insertion ot a sliding rod 32 upon one end of which 1 have assembled a threaded nut 32a, a coil spring 33 extending between washer 34 and the nut 32a at its lower end 30" of arm 30. lntermediate these extensions the arm 30 is provided with a contacting lug 30 arranged to contact with the arm 19. Rod 32 at its other extremity is pivoted at one extremity 34a of bell crank 34;, which at its central apex portion is pivoted at 34th to the door. At the other extremity 340, the bell crank 3e is pivotally attached to operating rod 35 terminataing in the engaging knob 36 which portion rides into the l, shaped slot 3? oi plate 37 attached to the door, the lever mechanism composed of the rods 32,

rename 35 and bell crank 34 being similar to that disclosed in my prior patent mentioned above. When the knob 36 -is moved into the lower angularly disposed portion ont slot 37 the pawl 18 will be moved into engagement with the ratchet 16, the spring 33 providing a yielding element whereby it the pawl is not in alinement with a notch in the ratchet it may ride on the ratchet until a notch is alined with it. 'llhis also permits for opening movement of the door against the action of spring 33, intentionally or accidentally.

llt will be apparent that with the lever actuating mechanism just described out of 8U operative position, a slight opening movement of the door will serve to disengage the pawl 18 and move the same to release position wherein it will be yieldably held by the scar 20. @nly a slight pressure on the arm 19 is necessary to move the pawl from release position into engagement with the ratchet.

`l do not wish to he restricted to the Storm of my invention disclosed and shown, save T3@ as l have delined itinv the appended claims.
